Document 636 -1 Power Inductor - GA3252-AL For National Semiconductor LM3433 LED Driver * High current surface mount toroidal power inductor * Specified by National Semiconductor for 2 A to 14 A output applications Core material Ferrite Terminations RoHS compliant tin-silver (96.5/3.5) over copper. Other terminations available at additional cost. Weight 11.6 g Ambient temperature -40C to +85C with Irms current, +85C to +125C with derated current Storage temperature Component: -40C to +85C. Tape and reel packaging: -40C to +80C Resistance to soldering heat Max three 40 second reflows at +260C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 85% relative humidity) Mean Time Between Failures (MTBF) 26,315,789 hours Packaging 200 per 13 reel Plastic tape: 44 mm wide, 0.5 mm thick, 32 mm pocket spacing, 10.4 mm pocket depth PCB washing Only pure water or alcohol recommended Part number1 GA3252-AL_ Inductance2 20% (H) 12.0 DCR max3 (Ohms) 0.017 SRF typ4Isat (A) (MHz) 10% drop 20% drop 20 6.5 8.0 5 Irms (A)6 30% drop 20C rise 40C rise 13 6.5 10 1. When ordering, specify termination and packaging codes: GA3252-ALD Termination: L = RoHS compliant tin-silver over copper. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: D = 13 machine-ready reel EIA-481 embossed plastic tape (200 per full reel). B = Less than full reel In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance tested at 100 kHz, 0.1 Vrms on Agilent/HP 4192A. 3. DCR measured on a Keithley 580 micro-ohmmeter or equivalent. 4. SRF measured on an Agilent/HP 8753ES network analyzer. 5. DC current at which the inductance drops the specified amount from its value without current. 6. Current that causes the specified temperature rise from 25C ambient. 7. Electrical specifications at 25C.
